## Summary description

A 90° pipe elbow made of PP-R (polypropylene random copolymer) for 16 mm piping, suitable for changing direction in plumbing and heating systems. Manufactured by Alkotest (model KN9016), it connects PP-R pipes of the same diameter, offering corrosion-resistant, chemical-stable jointing for potable water, heating circuits, or industrial piping installations.

## Long description

Pipe elbow 90° 16 mm PP-R Alkotest KN9016 is a compact 90-degree fitting made from polypropylene random copolymer (PP-R) designed for use with 16 mm diameter PP-R piping. It provides a right-angle change of direction for plumbing, heating and industrial installations and is suitable for systems where corrosion resistance and chemical stability are required. The fitting is made to join pipes of the same nominal diameter and is intended for permanent, solvent-free welded or fusion-joint connections commonly used in potable water and heating circuits.
Advantages
The PP-R construction offers long-term resistance to corrosion and common chemicals encountered in potable water and heating systems, keeping flow paths free from rust and scale. Its standardized 16 mm diameter ensures compatibility with other PP-R components of the same nominal size, enabling reliable fusion or socket welding connections. The simple 90° geometry allows efficient routing of pipes in confined spaces while maintaining consistent internal flow characteristics.
Suitable for
 Domestic and commercial potable water supply lines
 Heating circuits and underfloor heating manifolds
 Small-diameter industrial piping and process lines
 Connections inside compact enclosures, cabinets, and service shafts
Key specifications
 Material: polypropylene random copolymer (PP-R)
 Angle: 90° elbow
 Nominal pipe diameter: 16 mm
 Connection method: fusion/welding (socket fusion or butt fusion as applicable)
 Application temperature range: suitable for cold and hot water systems and heating circuits (refer to system design limits)
 Resistance: corrosion- and chemical-resistant within typical potable water and heating media
How to use
Select the elbow to match 16 mm PP-R piping and prepare the pipe ends by cutting square and removing burrs. Heat the pipe and fitting ends with an appropriate PP-R fusion tool according to the tool manufacturer's instructions, then join the parts at the correct alignment and hold until the joint cools and sets. Allow sufficient cooling time before pressurizing the system. Ensure that all welding is performed by trained personnel and in accordance with local plumbing and building codes.
Usage recommendations
Use compatible PP-R installation tools and follow fusion-welding procedures specified for PP-R materials. Verify system pressure and temperature requirements against the installed components' ratings and allow for thermal expansion in heating circuits. Avoid exposing joints to mechanical stress or tension during curing and use appropriate supports and clamps to prevent sagging or bending at the elbow.
